The current implementation (as well as the one in LinearAlgebra) calls the balancing function

ExponentialUtilities.jl/src/exp.jl

Line 24 in dc1e104

ilo, ihi, scale = LAPACK.gebal!('B', A) # modifies A

which we don't have a generic implementation of. It would be great to have one. It shouldn't be a difficult function to implement but might be worth noticing that there is already one available here https://github.com/RalphAS/GenericSchur.jl/blob/master/src/balance.jl

andreasnoack changed the title ~~Generic mutating exp~~ Generic mutating exp!
